VALVE DEVICE FOR WATER-CLOSETS.

Specification of Letters Patent.

Application filed December 21, 1907.

Patented July e, 1909.

semi No. 407,605.

To all whom 'it may concern.'

Be it known that I, PATRICK J. MADDEN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Valve Devices for Taten Closets, of which the following is a specification.

The present invention relates to a valvedevice of the class shown in U. S. Letters Patent No. 569,559 which were granted to me October 13, 1896 and in which an inlet valve and an outlet valve are arranged to operate reciprocally so that when the outlet` valve is seated the inlet valve is unseated, and vice versa.

The present invention has nothing to do with the inlet valve but relates solely to the outlet valve and consists in the features of novelty that are hereinafter described.

In the accompanying drawing, which is made a part of this specification; Figure l. is a vertical section of a fragment of the rear portion of the bowl of a waterecloset and a sectional elevation of a valve-device, enibodying the invention. Fig. 2 is a rear elevation of a fragment of the bowl, the valvedevice being omitted.. Fig. S is an elevation of a non-circular nut.

A represents a fragment of a water-closet bowl, made of pottery. In its upper rear portion (or elsewhere if desired) is formed a chamber B having one or more openings for the outlet of water so located as to meet the requirements of the particular type of closet to which the invention is applied. The drawing shows two openings, o, leading from opposite sides of the upper portion of the chamber, for supplying the hollow riin, A, of the bowl, an opening, b, leading downward from the bottom of the chamber for supplying the jet opening (not shown) and one of three openings, 722, leading downward. from the bottom of a portion of the chamber which projects into the bowl. But, as before intimated, the number or location of these water outlet openings is not material.

The rear wall B of the chamber is provided with an opening b3 which is circular, save for a radial notch, b4, formed in 'the wall of the opening, which increases, in one diametrical direction, its otherwise uniform diametrical dimensions. The front wall, B2, of the cham ber has through it an opening, b, which is considerably restricted in size, as compared with the opening 3.

The valve-device .has a casing which occupies the chamber and the opening b3, and comprises a cylindrical externally threaded rear portion., C, a cylindrical front portion,

l', which is closed at its front end, save for an opening through which passes the stem, D, of the outlet valve, E, and struts or bridge pieces, C2, connecting the parts C and C, the spaces between the adjacent struts being in fact large ports through the sides of the casing. The front end of the casing carries a sleeve, C3, which surrounds the valve-stem., D, snugly, and which also occupies the opening b5 through the front wall BZ of the chame ber, and an elastic packing ring F is placed around the sleeve, between the inner end of the casing and the inner wall of the chamber, so that when the casing is forced inward a water-tight joint will be formed between the inner end of the casing and the front wall of the chamber.

Surrounding and having engagement with the externally threaded portion C of the casing is a nut G, which is located within the chamber and bears against a shoulder within the chamber, the shoulder, in the instance shown in the drawing being, in fact the inner face of the rear wall of the chamber. The nut is non-circular- As shown in the drawing it has oppositely located fiat sides, g, one of which is engaged by a flat surface b on the interior of the chamber, whereby it is prevented from turning.

His a second nut, surrounding and having threaded engagement with the rear portion of the casing on the outside of the chamber, and adapted to bear against the rear wall of the chamber through the medium of a packing ring t, whereby a water-tight joint is made between the chamber and casing.

The term chaniiber is herein used to designate the hollow portions of the bowl which contains the valvedevice, but I desire to have it understood that any space or cavity adapted to contain the valve-device and having an opening at one end for admitting the valve-device and an opening at the other end for the passage of the stem of the valve is within the scope of the invention, so far as this so-called chamber is concerned.

In assembling the parts thus far described, the parts of the valve-device are first assembled in the valve-casing and properly adjusted. lll/lith the bowl resting on its back and the chamber B in vertical position, the nut, G, is inserted through the opening b-l, the nut being meanwhile held in the diarneti'ical plane et the notch b and with its 'flat side or sides vertical. After passing through the opening;` the nut is brought to bear upon the rear wall, B', with its ilat side opposite the flat surface t in the chamber, whereby it is prevented lroni turning'. lll/lith the packing ringl F in place on the sleeve C3, the casing' is slipped tlirough the opening b3 and nut, G, until its threaded portion C s the nut. The casing' is then screwed through the nut until ythe sleeve 'LIB has entered the opening' if and the packing ring' F is conipressed sulii* ciontly to torni the desired water-tight oint between the end ot' the casing` and the iront wall ci the chamber. 'llhe nut H is then turned heine, compressing' the packing' ri ,e h and torininl a waier-tnrht joint between the casing' and Lne rear wall ci the chamber.

The joint between the valve-stem D and the walls oi the opening' in the end olj the casingl through which it passes is made tie'ht by an elastic packing` l, located within the casing. Said parel-fling;` has a portion i in the forni oi' a l'rustuin and a portion i in the lorin ol a radial tlange at the base et the lrustuni, the frustuin being provided with an opening' through which the valveste;n passes u 'th a snug lit. ''hc trustuin tapers to a feather edge so that the pressure the water surrounding; it tends to press it hilly against the valve stein and j'n'eveni'; lea past it. It is found that such a packing` is easily' 'ijured unless it is protected and this is particularljT true it it is used in the position shown in the drawing because of 'the repeated blows to which it would be subjected by the valve E. 'llo prevent its being injured, a shield in the lorin el a complementary hollow inetallie frustunr d is interposed between it and the valve E the base tlang'e of the metallic trustuni resting' upon the base llang'e of the elastic frustuin. The elastic lrustuin serves also to cushion the stroke of the valve and lessen the noise incident to the operation ot' the valve. Furthermore, the shield completely covers and conceals the elastic h'ustuin, the opening' through the shield being just sutilcient to receive the valve stein, so that when the valve is bearing' against the hollow frustuin, the pressure oi the latter' upon the elastic frusturn serves to compress it and thereby more iirinlv torce it against the stern G. 'ihe frusta are loose within the casing' so as to be h'eeljT movable relativelv thereto and partake ol the nwvenient ot the valve stein which the elastic lirustuin lits tightlyT and this has the advantage of practically eliiniand the valve stein with the result that the wearing or the elastic frustuin is practicalljr eliminated.
